Kawasaki Service Manual Versus Cyclepedia Online manual

Hi DT, Sorry I don't know about the manual thing, but Provided you document and photograph parts as you remove them, it is basicaly just a metal jigsaw puzzle, not too hard really. You will need the torque specs for putting stuff back together though. And you will need the specs for checking wear limits and tolerances.
I completely dissasembled, reconditioned and rebuilt an old Kawasaki 250 I had years ago without a manual. I just bought a bunch of clear resealable bags and drew diagrams of what I was taking apart and put it in the bag with the piece/pieces as I took them off. Worked well. The main thing is to make sure it's all spotlessly clean and all of the parts are contained (so you don't loose any).
